Mine pressure bump prevention technology of coal mining face in thick seam of mine deep structure area

in order to solve the mine pressure bunp prevention and control problems of the coal mining face in tructure area of Noc.12 seam in Zhaogezhuang Mine.based on No.2337 E coal mining face as a case.the posstblity of the mine pressure bump occured in the coal mining face was analjzed based on the thee factors ofthe geological condttons ,the structure stress distrbution and the mining technofogy.The comprehensive index nethod .the possility index diagnosis method and the empirical nalogy mefnod were appied to the systematic evaluation on the danger of No.2337 E cal mining face.There was a medum pressure bump danger determined for thecoal nining face .With the sectional defect type basting pressurereleased, borehole pressure released and the water injection pressure released measurescerain pressure released was conducted in diferent danger areas of the coal mining face The conbination withthea lling cuting method and the stress on-ine montorig and measuring technology was appied to thereal time montoring and measuring of the danger rea .The mine pressure bump occured was effcively reduced and he safety mining of the coal mining face in the thick seam of the deep structure area.
